Hi both and thanks for the help.
I tried the default calibration factor, 2.0, and another one, 1.16.
I think it shoud affect the precision of the sensor, but it shouldn’t make the sensor unavailable, or am I wrong?
About log, I did exactly that immediately after petro’s reply.
In log I have now few debug lines indicating temperature and humidity sensor update, and…
…ok, I think that I finally found the problem!
One of my sensor didn’t have unit_of_measurement, so it’s value was unavailable and the mold_sensor got broken.
Now it’s working!!!
Thank you very much for pointing me in the right direction.
